,COMBINED PUMP VALVE AND CAP.

Specification of Letters Patent.

Patented May 28, 1907.

Application filed July 27,1906. Serial 328,093.

T0 at whmn it may concern:

Be it known that I, ARTHUR RICHARD F0- LEY, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented a new and useful Combined Pump Valve and Cap, of which the following is a specification.

This invention relates to lift valves for pumps and has for its object to provide a comparatively simple and inexpensive dev1ce of this character having a removable packing or bearing surface for engagement with the valve-seat whereby the former may be readily detached when worn or otherwise injured and replaced by new bearing surfaces thereby materially lengthening the life of the valve.

A further object of the invention is to provide a valve having a yieldable packing formed in two sections provided with interlocking parts, said section being retained in position by a metallic cap or casing which forms the top of the valve. 1-

A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability and efficiency as well as to reduce the cost of manufacture.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure 1 is a transverse sectional view of alift-valve constructed in accordance with my invention. Fig. 2 is a perspective view showing the cap and removable packing disks detached.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved device consists of a cap or casing 5 provided with a depending marginal flange 6 defining a chamber or compartment 7 for the reception of the yieldable packing,

as shown.

The packing is preferably formed in two sections 8 and 9 one of which is provided with a transversely disposed dove-tailed locking lip 10 adapted to engage a correspondingly shaped groove or recess 11 formed in the ad jacent face of the section 9 whereby the lower section 9 may be readily removed when the same becomes worn or otherwise injured and replaced by a new disk thus materially lengthening the life of the valve. The casing 5 is provided with a central perforation 12 for the reception of the usual valve stem or spindle, there being similar perforations 13 formed'in the sections 8 and 9 and disposed in aliner'nent with the perforation 12 to per mit the passage of the stem, as shown. It will thus be seen that when the lower diskor bearing face 9 becomes worn or otherwise injured from constant use the same may be readily removed by sliding said disk laterally until the lip 10 is disengaged from the groove 11 after which a new section may be placed in position on the upper section 8 and the several parts fastened within the casing or housing.

The sections 8 and 9 are preferably formed of rubber, leather or other suitable yielding material but it is obvious that the upper section 8 may be constructed of metal and in some cases may be formed integral with the cap or casing. The caps may be made in different sizes and shapes so as to adapt the same to different styles of pumps and if de sired the fianges 6 may be inclined laterally into engagement with the yieldable packing strips thereby to assist in retaining said strips within, the compartment of the cap or casing.

From the foregoing description it will be seen that there is provided an extremely simple, inexpensive and eificient device admirably adapted for the attainment of the ends in view.

Having thus described the invention what is claimed is:

1. A valve comprising a casing provided with a depending marginal flange defining a compartment, a yieldable packing disk seated in the compartment and provided with a transverse dove-tailed locking lip, and a removable packing disk extending beyond the free edge of the flange and having a transverse groove formed therein for the reception of the locking lip the grooved packing disk being provided with a continuous uninterrupted bearing surface. I

2. A valve comprising a perforated casing provided with a depending marginal flange defining a compartment, superposed yieldable packing disks disposed within the compartment and provided with perforations disposed in aiinernent with the perforation in In testimony that claim the foregoing as the ca one of said packing disks being eX- my own, I have hereto affixed my signature [0 tende below the free edge of the flange and in the presence of two witnesses.

provided With a transverse dove-tailed locking lip adapted to engage a corresponding ARTHUR RICHARD FOLEY groove formed in the adjacent packing disk, Witnesses:

said grooved disk being provided With a HOWARD O. CAULDWELL,

smooth continuous bearing surface. WILLIAM H. GOLDING.
